The Post Office Savings Bank, or "Postsparkasse", has a facade constructed of granite and marble plates held in place with alumimum rivets, giving the building the appearance of a giant safe. The main counter hall has a curving glass ceiling, aluminum heating units and a glass-lined floor to allow light to penetrate lower floors. A second glass roof protects the main counter hall ceiling from the elements. The main counter hall serves the public, while a second, smaller counter area in the rear of the building serves business clients. The areas around the main counter hall contain the bank offices and a circulating corridor. The offices are constructed of mahogany and have moveable partition walls, while the public spaces are constructed of granite, marble and metal.
